Final answer:
The absolute maximum value of sin(x) within the interval [0,2π] is 1, which occurs at π/2 radians or 90 degrees.
Step-by-step explanation:
The absolute maximum value of sin(x) within the interval [0,2π] is 1. The sine function oscillates between -1 and +1, and reaches its maximum value of 1 at an angle of π/2 radians, or 90°. Any value of sin(x) will not exceed this, so the answer is option B) 1.
